我在一个CentOS 7虚拟机上运行了symfony 2.8。现在，当我试图访问我的网站时，我遇到了一个内部服务器错误。当我检查日志时，上面写着：
Request exceeded the limit of 10 internal redirects due to probable configuration error
我将apache中的LogLevel设置为trace3，看起来app.php周围有一大堆重定向。我不确定发生了什么。我还没有修改symfony附带的.htaccess文件。这是.htaccess文件中的mod_rewrite块：
<IfModule mod_rewrite.c>
RewriteEngine On
# Determine the RewriteBase automatically and set it as environment variable.
# If you are using Apache aliases to do mass virtual hosting or installed the
# project in a subdirectory, the base path will be prepended to allow proper
# resolution of the app.php file and to redirect to the correct URI. It will
# work in environments without path prefix as well, providing a safe, one-size
# fits all solution. But as you do not need it in this case, you can comment
# the following 2 lines to eliminate the overhead.
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::'2$
RewriteRule ^(.*) - [E=BASE:%1]
# Sets the HTTP_AUTHORIZATION header removed by apache
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect to URI without front controller to prevent duplicate content
# (with and without `/app.php`). Only do this redirect on the initial
# rewrite by Apache and not on subsequent cycles. Otherwise we would get an
# endless redirect loop (request -> rewrite to front controller ->
# redirect -> request -> ...).
# So in case you get a "too many redirects" error or you always get redirected
# to the start page because your Apache does not expose the REDIRECT_STATUS
# environment variable, you have 2 choices:
# - disable this feature by commenting the following 2 lines or
# - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
# following RewriteCond (best solution)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app'.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .? - [L]
# Rewrite all other queries to the front controller.
RewriteRule .? %{ENV:BASE}/app.php [L]
</IfModule>
这是我的httpd.conf（不要担心任何安全问题。这是一个仅用于开发目的的本地安装）

我看不出这种重定向一直发生在哪里。我错过了什么？
将上次RewriteRule更改为：
RewriteRule !/app'.php$ %{ENV:BASE}/app.php [L,NC]
